+## Concepts
+
+There are over 50000 Linux packages and even more applications. It is simply not possible to write an AppArmor profile for all of them. Therefore a question arises: *What to confine and why?*
+
+We take inspiration from the [Android/ChromeOS Security Model][android_model] and we apply it to the Linux world. Modern [linux security implementation][clipos] usually consider a core base image with a carefully set of selected applications. Everything else should be sandboxed. Therefore, this project tries to confine all the *core* applications you will usually find in a Linux system: all systemd services, xwayland, network, bluetooth, your desktop environment... Non-core user applications are out of scope as they should be sandboxed using a dedicated tool (minijail, bubblewrap...).
+
+This is fundamentally different from how AppArmor is used on Linux server as it is common to only confine the applications that face the internet and/or the users.
